‘At the same time we find the explanation of how there can be groups of religious phenomena which do not belong to any special religion; it is because they have not been, or are no longer, a part of any religious system. If, for some special reason, a cult happens to be maintained while the group of which it was part of disappears, it survives only in a disintegrated condition. That is what has happened to many agrarian cults which have survived themselves as folklore. In certain cases, it is not even a cult, but a simple ceremony or particular rite which persists this way. This is the case with persists in this way.
